Born in Preston, Lancashire, Brazil began writing in her thirties and eventually published nearly fifty novels, most set in imaginative boarding schools such as Cliff House and Chipstone. She possessed a keen ear for schoolgirl slang and an eye for authentic detail, which made her stories feel fresh and immediate to young readers.
Her major works include The Fortunes of Phillipa (1906), her first great success; The Nicest Girl in the School (1909); For the Sake of the School (1911); The Jolliest Term on Record (1912); The Madcap of the School (1917); and A Patriotic Schoolgirl (1918). Popular throughout the early twentieth century, her stories remain charming portraits of Edwardian girlhood and helped define an entire genre of children's literature.
